The first step towards remedying this is to unhook the negative battery cable and remove the engine’s cover and set it aside.

A 5/16-inch nut driver works best for loosening the retainers. However, a flat blade screwdriver can be utilized as well. The clamps at the turbo can be tough to reach— patience is required.

Its larger diameter and smoother bends greatly help in getting air to the turbocharger. Start with the turbo inlet side first, finishing at the mass airflow sensor. Leaving all of the clamps loose until the tube is fully fitted with reduce frustration greatly.

When installed, the air box functions with the same level of sealing as the factory box, albeit with reduced airflow.
